# 一键启动 FastAPI 后端:
# - 自动创建/复用虚拟环境(.venv
# - 自动安装 requirements.txt 依赖
# - 自动启动 uvicorn默认开启 --reload
#
# 用法示例:
# ./run.sh # 默认 host=0.0.0.0 port=8000 env=dev reload=on
# ./run.sh --env prod # 使用 .env.prod若存在且可被 source
# ./run.sh --port 9000 # 改端口
# ./run.sh --no-reload # 关闭热更新
# ./run.sh --install-only # 只安装依赖,不启动
usage() {
cat <<'EOF'
用法:
./run.sh [--env dev|prod] [--host 0.0.0.0] [--port 8000] [--no-reload] [--skip-install] [--install-only]
参数:
--env dev|prod 优先尝试加载 .env.dev 或 .env.prod如果存在
--host <host> uvicorn host默认 0.0.0.0
--port <port> uvicorn port默认 8000
--no-reload 关闭 uvicorn --reload
--skip-install 跳过依赖安装(默认会安装/更新 requirements.txt
--install-only 只安装依赖,不启动服务
-h, --help 显示帮助
说明:
- 若你的 .env.* 不是 shell 可 source 的格式(例如包含空格/特殊字符未加引号),建议改成 KEY=value 形式。
- 启动后访问:
/healthz 健康检查
